I asked this question in the cichlids group, but got no responses, so
I'm asking here.

I have a 120-gallon community tank that includes 3 red-hump eartheaters
(2F, 1M). At least one of the females has had babies, but they all
disappeared (no surprise) within a day of when I first saw them swimming
around her mouth.

I now have a 20-gallon breeding tank set up so I can isolate the females
next time they start brooding. I want to keep the tank up and running
with fish that won't eat the eartheater fry that someday should be
there. Is there any such fish? My LFS suggested cory cats.

Right now, I have a one-inch albino bristlenose ancistrus, 7 cardinal
tetras, and 4 juvenile platies that I removed from a 7-gallon tank that
I'm turning into a hospital tank. Can they safely be left in when the
female eartheater moves in, or do I need to move them somewhere else?
